+# ATLAS: A High-Difficulty, Multidisciplinary Benchmark for Frontier Scientific Reasoning
+
+
+## 📊 Overview
+
+**ATLAS (AGI-Oriented Testbed for Logical Application in Science)** is a high-difficulty, multidisciplinary benchmark designed to evaluate frontier scientific reasoning capabilities of Large Language Models (LLMs). As existing benchmarks show saturated performance, ATLAS provides a reliable measuring stick for progress towards Artificial General Intelligence.
+
+### 🌟 Key Features
+
+- **🎯 800+ Original High-Quality Questions**: All questions are newly created or significantly adapted to prevent data contamination
+- **🔬 7 Core Scientific Domains**: Mathematics, Physics, Chemistry, Biology, Computer Science, Earth Science, and Materials Science
+- **🏛️ 25+ Leading Institutions**: Contributed by PhD-level experts from top universities and research institutions
+- **💎 High-Fidelity Answers**: Complex, open-ended answers involving multi-step reasoning and LaTeX expressions
+- **🛡️ Contamination-Resistant**: Rigorous quality control with multi-round expert peer review and adversarial testing
+
+### 📈 Leaderboard Highlights
+
+Latest results evaluated with **OpenAI-o4-mini** as judge (Public Validation Set):
+
+| Rank | Model | Organization | Accuracy (Avg) |
+|------|-------|--------------|----------------|
+| 1 | OpenAI GPT-5-High | OpenAI | 42.9% |
+| 2 | Gemini-2.5-Pro | Google | 35.3% |
+| 3 | Grok-4 | xAI | 34.1% |
+| 4 | OpenAI o3-High | OpenAI | 33.8% |
+| 5 | DeepSeek-R1-0528 | DeepSeek AI | 26.4% |
+
+> 📝 **Note**: Results show that even the most advanced models struggle with ATLAS, demonstrating its effectiveness as a frontier benchmark.

+
+## 🚀 Quick Start
+
+### Installation
+
+```bash
+pip install opencompass
+```
+
+### Load Dataset
+
+```python
+from datasets import load_dataset
+
+# Load ATLAS dataset
+dataset = load_dataset("opencompass/ATLAS")
+
+# Access validation split
+val_data = dataset['val']
+print(f"Validation samples: {len(val_data)}")
+
+# Access test split (for inference only)
+test_data = dataset['test']
+```
+
+### Basic Evaluation Setup
+
+```python
+from mmengine.config import read_base
+
+with read_base():
+    from opencompass.configs.datasets.atlas.atlas_gen import atlas_datasets
+
+# Update your judge model information
+atlas_datasets[0]["eval_cfg"]["evaluator"]["judge_cfg"]["judgers"][0].update(dict(
+    abbr="YOUR_MODEL_ABBR",
+    openai_api_base="YOUR_API_URL",
+    path="YOUR_MODEL_PATH",
+    key="YOUR_API_KEY",
+    # tokenizer_path="o3",  # Optional: update if using a different model
+))
+```
+
+### Evaluate on Test Split
+
+```python
+from mmengine.config import read_base
+
+with read_base():
+    from opencompass.configs.datasets.atlas.atlas_gen import atlas_datasets
+
+# Configure for test split
+atlas_datasets[0]["abbr"] = "atlas-test" 
+atlas_datasets[0]["split"] = "test"
+atlas_datasets[0]["eval_cfg"]["evaluator"]["dataset_cfg"]["abbr"] = "atlas-test"
+atlas_datasets[0]["eval_cfg"]["evaluator"]["dataset_cfg"]["split"] = "test"
+```
+
+> ⚠️ **Important**: The test split is only supported for inference mode. Use `-m infer` flag when running OpenCompass.
+
+### Run Evaluation
+
+```bash
+# Evaluate on validation set
+python run.py configs/eval_atlas.py
+
+# Evaluate on test set (inference only)
+python run.py configs/eval_atlas.py -m infer
+```

+
+## 📚 Dataset Structure
+
+### Data Fields
+
+- `name_en`: Subject name in English (e.g., "Biology", "Physics")
+- `question`: The scientific question/problem statement
+- `answer_ideas`: Reasoning ideas and approaches for solving the problem
+- `refined_standard_answer`: List of standard answers (may contain multiple sub-answers)
+- `sub_subject_name`: Specific sub-discipline (e.g., "Molecular Biology", "Quantum Mechanics")
+
+### Data Splits
+
+| Split | Count | Purpose |
+|-------|-------|---------|
+| **Validation** | 300+ | Public evaluation, reproducible results |
+| **Test** | 500+ | Hidden evaluation, contamination-resistant |
+
+### Example Data Point
+
+```json
+{
+  "name_en": "Biology",
+  "question": "Explain how CRISPR-Cas9 gene editing works at the molecular level...",
+  "answer_ideas": "[\"Cas9 protein binds to guide RNA...\"]",
+  "refined_standard_answer": [
+    "1. Guide RNA (gRNA) directs Cas9 to target DNA sequence...",
+    "2. Cas9 creates double-strand break...",
+    "3. Cell repairs through NHEJ or HDR pathways..."
+  ],
+  "sub_subject_name": "Molecular Biology and Biotechnology"
+}
+```
+

+
+## 🎯 Evaluation Protocol
+
+ATLAS uses an **LLM-as-Judge** evaluation framework with the following characteristics:
+
+### Judge Model
+
+- Default: **OpenAI-o4-mini** (for leaderboard consistency)
+- Customizable: You can use your own judge model
+
+### Evaluation Process
+
+1. **Model Inference**: Generate answers in structured JSON format
+2. **Answer Extraction**: Parse final answers from model outputs
+3. **LLM Judging**: Compare candidate answers with standard answers
+4. **Scoring**: Calculate accuracy and pass@k metrics
+
+### Answer Format
+
+Models should output answers in the following JSON format:
+
+```json
+{
+  "answers": [
+    "answer to sub-question 1",
+    "answer to sub-question 2",
+    ...
+  ]
+}
+```
+
+### Evaluation Metrics
+
+- **Accuracy (Avg)**: Average correctness across all questions
+- **mG-Pass@2**: Majority voting accuracy with 2 samples
+- **mG-Pass@4**: Majority voting accuracy with 4 samples
